Filed: 1989-09-13
Abstract: PURPOSE: To join without using flux by coating each of two metallic surfaces with a lead containing layer and a tin alloy layer on the lead containing layer, heating surfaces with causing each tin alloy layer into contact each other above the eutectic temp., forming a localized liquid and then solidifying. CONSTITUTION: A first material layer 20 of Pb or Pb-Sn alloy is adhered on a copper part 10 of parts to be bonded or metal coated substrates. A second different material layer 30 is adhered on each layer 20. The layer 30 is made of tin or an alloy rich in tin, these first and second different materials are selected so as to form an eutectic liquid layer. The tin layers 30 are caused into contact each other, this composite body is heated above the eutectic temp. By this method, mutual diffusion is caused between the layer 30 material and the layer 20 material. When cracking is imparted to a Sn-oxide of surface by applying a low pressure in bonding, the liquid completely wets a joining place. By this method, improved transition liquid phase bonding, in which the interconnection of two metallic surfaces is mutually made, is obtained.

Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent a ROM from being pulled out by being caught by a projection part in trying to pull it out and prevent a dishonest act by forming the projecting part on a front cover body in a position matched with right above the ROM. SOLUTION: A figure A is an prospective view of a control box 1 having a partial cutaway view and a projection part 100 is formed on a front cover body 10 in a position matched with right above a ROM 101 installed on a control substrate 12. When the control box 1 is assembled, (cf. figure B) the projection part 100 may be in contact with the ROM 101, however, it is preferable to form a clearance impossible of pulling out the ROM 101 by taking account of the heat radiation. When the projection part 100 is formed in this way, the ROM 101 is prevented from being pulled out by drawing out a pin from a socket in a state of having no clearance right above. This constitution eliminates any possibility of exchanging the ROM with a false one. The formation of such a projection part 100 allows an air hole 102 to be formed right above the ROM so as to radiate the heat.
